Objectives: Inappropriate prescription of antibiotics contributes to antibiotic resistance. Therefore, the objective of this study was to determine the awareness, attitudes, and intention to practice of dentists prescribing antibiotics in Colombia in order to design a virtual learning environment on this subject. Methods: In a descriptive study across seven cities, 700 dentists from different Colombian cities were requested to complete a validated questionnaire containing five sections: general information, awareness on antibiotic effectiveness and antibiotic resistance, attitudes regarding prescription decision, intention to practice concerning clinical cases, and complementary information. The level of awareness, attitudes, and intention to practice was determined and Chi-square test was used to determine the existence of significant differences among cities. Results: The majority of dentists showed a medium level regarding the number of correct answers on awareness (62.4 percent) and attitudes (88.7 percent) and a high level on intention to practice (91.7 percent). Common errors within the awareness section included the meaning of the term "antibiotic resistance" (35 percent) and most dentists were not convinced that such resistance could be derived from prescription of antibiotics (51.2 percent). In the attitudes section, only 45 percent declared that they prescribe antibiotics based mainly on symptoms, and the intention to practice section showed a significant percentage of unnecessary prescription (51 percent for pacemaker users) or absence of prescription (53.9 percent for ventricular septal defect) in antibiotic prophylaxis for infectious endocarditis (IE). Conclusion:The dentists interviewed should be trained and made aware of antibiotic resistance, microbiological and clinical foundations, and current antibiotic prophylaxis guidelines.

Appropriate antibiotic prescription contributes to reducing bacterial resistance; therefore, it is critical to provide training regarding this challenge. The objective of this study was to develop a virtual learning environment for antibiotic prescription and to determine its impact on dentists’ awareness, attitudes, and intention to practice. First, the learning content on multimedia resources was developed and distributed into three challenges that participants had to overcome. Then, a quasi-experimental study was performed in which the virtual learning environment was implemented on dentists from seven Colombian cities. The median of correct answers and the levels of awareness, attitudes, and intention to practice were compared before, immediately after, and 6-months post-intervention. Wilcoxon signed-rank and McNemar’s tests were used to determine the differences. A total of 206 participants who finished the virtual learning environment activities exhibited a favorable and statistically significant impact on the median of correct answers of awareness (p < 0.001), attitudes (p < 0.001), and intention to practice (p = 0.042). A significant increase occurred in the number of participants with a high level of awareness (p < 0.001) and a non-significant increase in participants with high levels of attitudes (p = 0.230) and intention to practice (p = 0.286). At 6 months, the positive effect on the median of correct answers on awareness and intention to practice persisted (p < 0.001); however, this was not evident for attitudes (p = 0.105). Moreover, there was a significant decrease in the number of participants who showed low levels of awareness (p = 0.019) and a slight increase in those with high levels of the same component (p = 0.161). The use of a virtual learning environment designed for dentists contributed to a rapid improvement in awareness and intention to practice antibiotic prescription; however, their attitudes and information retention need reinforcement.

Con la biomecánica de ortodoncia convencional no siempre se obtienen los resultados en el tiempo requerido sobre todo en casos complejos, para ello se emplean miniimplantes para darle solución a estas dificultades. Identificar y describir los factores que inciden sobre el éxito y/o fracaso de mini-implantes dentales en ortodoncia es el objetivo de la presente revisión sistemática exploratoria. Se emplearon las bases de datos: PubMed, Google Schoolar, Science Direct y Clinical key. Fueron analizados artículos en inglés y/o español, ensayos controlados aleatorizados, ensayos clínicos prospectivos y estudios clínicos retrospectivos. Las búsquedas iniciales identificaron 612 títulos y resúmenes sobre miniimplantes de los cuales 480 fueron excluidos, los 132 artículos restantes fueron recuperados y analizados, 22 cumplieron con los criterios de selección, finalmente solo N=6 artículos cumplieron para el análisis de datos. Todos los estudios identificados fueron aquellos de sistema autoperforante, con cargas inmediatas en el maxilar superior, todos los mini-implantes eran de titanio y de diferentes casas comerciales. El material, fabricante y diámetro de los mini-implantes no inciden sobre las tasas de éxito, la proximidad de una raíz no se asocia con la falla del mini-implante y se considera un fracaso del mini-implante si presentaba alguna movilidad posoperatoria.

Introducción: El granuloma telangiectásico es una neoplasia benigna de origen epitelial y contenido vascular que se presenta en cavidad oral, de crecimiento lento. Su etiología es atribuible a trauma físico, alteraciones hormonales y al uso de medicamentos, además es inducido por presencia de cálculos y deficiente higiene oral. Objetivo: describir las características clínicas y patológicas de un granuloma telangiectásico presente en cavidad oral, su patogénesis y el manejo de terapéutico del caso. Presentación del caso: Paciente de 35 años que acude a consulta por presentar una lesión tumoral, en sector anterosuperior derecho, afectando la estética de la paciente. Se realizó excisión quirúrgica y al realizar el estudio histopatológico se confirmó diagnóstico de granuloma telangiectásico. Conclusión: Los profesionales de la odontología deben conocer todos los aspectos relacionados con el granuloma telangiectásico, etiopatogenia, características clínicas e histológicas, con el objeto de identificar esta patología, establecer diagnósticos diferenciales y poder brindar un diagnóstico adecuado y por consiguiente un plan de tratamiento específico para cada caso.
